| Duo 210/230: fancy artwork on early PG&E chips? | |
| Posted by: Arbee on 2025-02-02 14:46:39 As part of research for the upcoming addition of all of the 68030 and 040 Duos to MAME, I ran across this page https://www.dobreprogramy.pl/@macminik/powerbook-duo-best-of-both-worlds,blog,39291 with an interesting photo of a Duo 210/230 logic board. The PMU chip doesn't have the normal text-only markings, there's what appears to be line art of a power station with lightning bolts coming out of it. Does anyone have a Duo 210/230 where the chip has those markings and can post a higher-res picture? I know that sort of line art was common internally at 90s Apple, but I haven't seen it out in a production machine before. | |
| Posted by: mdeverhart on 2025-02-02 16:44:36 That’s pretty cool! My 230 that I recapped has the normal text-only markings. Recapping my other 230 is low on my list of projects, but I’ll post pictures if I find the line art in that one. | |
| Posted by: aladds on 2025-02-04 11:49:18 Sadly my 230 (1993, 6th week, Cork) does not have the cool graphic. (Also sadly this machine does not fully work, it will not spin up a hard disk. At some point I will re-attempt to repair it) | |
| Posted by: pl212 on 2025-02-04 12:39:51 Looking at the image on that Polish blog, I suspect it's a scan from MacUser or Macworld, either of which might have had access to prototype machines to prepare articles given print's long lead times. You could verify this by checking the issues -- too busy to do so now -- but the typography and the brushed metal background makes me think they're from a magazine of that era. | |

December 1992 Edit: It doesn't even have a battery connector! | |
| Posted by: Arbee on 2025-02-04 13:16:47 Nice detective work! And I appreciate the much more readable scans of the logic board. Looks like your PMU was manufactured 7 weeks after launch. It's possible a machine from right at launch (and thus with chips manufactured probably 6 months before that) might've gone out with the cool markings, but I'm certainly going to lower my expectations of one turning up. Incidentally, the chip marked "Sound controller" in that MacWorld image is actually the VRAM. | |
